1. Tonner based (Laser)
2. Liquid ink(Inkjet)
3. Solid ink
4. Dye-sublimation
5. Thermal
6. Inkless
7. UV

Impact printing technology
Some of these devices are rarely used. They are famous for its unique feature, common use in businesses where multi-part forms are printed. These are mostly comes under the impact printers and they gets printed mostly in mono chrome only. following are different  types of printers in impact printing
1. Daisy wheel
2. Dot matrix
3. Pen based plotter
4. Line printer
5. Typewriter-derived
6. Teletypewriter-derived
These are mostly comes under impact printers. These are commonly used for commercial purpose for its special feature to print multi-part forms.
